Perhaps you should try some spelling variations:
"modified passive convolution algorithms" » "modified passive evolution algorithm", "modified passive solution algorithm", "modified passive evolution algorithms", "modified passive solution algorithms", "modified adaptive convolution algorithms"
"modified caging convolution algorithm" » "modified caging evolution algorithm", "modified caging solution algorithm", "modified learning convolution algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive convolution algorithms\") OR (\"modified caging convolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified passive convolution algorithms ) OR ( modified caging convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive convolution algorithms") OR ("modified caging convolution algorithm"))*.
